Online Collaboration Tools

Sugarbox is a free web app which allows you to share any web app you are working on with anyone you wish to collaborate with.

To use it, you simply go to the web app, open it and then click on the Sugarbox bookmarklet, and you are ready to invite anyone to co-work with you, in real-time, on that app.

Once you are collaborating with someone you can see their cursor and their name in real time. You can text chat and annotate the screen.

A unique feature also allows you to easily record what's being shown on the screen, including your cursor movements, and can be easily shared with anyone. 

My comment: Excellent resource if you want to collaborate in real-time with someone else on the same app. 

Free to use.
